Mail.app problem

[Andreas Höschler]

Hi all,

we have a bunch of 10.2 Macs and one 10.4 Mac in our infrastructure. 
All are accessing a postfix mailserver running on Solaris.

One user - the one that is working with the 10.4 machine - now 
discovered something weird. The to header of all his incoming emails in 
Mail.app is no longer <username>@<ourdomain>.de but
	
	admin at viagra.com

I checked his emails with Mail.app from the other Macs (10.2). No 
problem, the to name is correct there. I checked his mails with 
thunderbird under Solaris. All fine! But on his 10.4 machine it looks 
like the mails had been addressed to admin at viagra.com. We are accessing 
our mail server via imap. I first thaught of a problem with postfix but 
since everything is fine on other machines it must be something 
specific to his machine or account.

I am totally clueless! Any idea?

Thanks a lot!

Regards,

   Andreas
